keyTyped not working?

Newbie & Debugging Questions
#1

Hi there!
So I working on the movement in my RPG.
Now it is so:
The Hero goes AND runs 16 Pixel(keyPressed).
But now I want that the Hero GOES 32 Pixel. And run 16 Pixel.

So I thought Im using keyTyped, when the Player push LEFT he move 32 Pixel.If he hold it pressed he mobe 16.
BUT it dont work :frowning:

Did I do something wrong in keyTyped?

[code=java]
public void keyTyped(int key, char c)
{
if(schalter.MovementAllowed){

        switch(key)
        {
            case Input.KEY_UP:
                    if(used==false){
		TypedUP=true; 
                    used=true;
                    lastDirection=3;
                    movement=true;
                 }
                 break;
      }

}
}



At my Movement Code
[code=java]
 if(TypedRIGHT && schalter.player_x<Kollision.getWidth()-40
          && blocked[schalter.player_x+48][schalter.player_y+48] == false
          && blocked[schalter.player_x+48][schalter.player_y+61] == false
          && schalter.player_x +32 != npcKollision_X[0]
          && schalter.MovementAllowed)
      {
         p.x=p.x-32;
         schalter.player_x=schalter.player_x+32;
      }

EDIT: Ok I think I know how to make it without. Im using this…Or not -.-"

keyTyped only runs when you press AND release the key. Unless you really want that behaviour, I suggest you override the keyPressed method instead.

EDIT: Wait a second, I guess you aren’t using a keylistener since the keyTyped method doesn’t have a single KeyEvent argument. Where did you get that code from?

#3

Umm…how are you getting input?
What defines “keyTyped(int key, char c)”? What is “Input”?

#4

Im using Slick. In

public void init(GameContainer gc)throws SlickException
{

I do


if (gc instanceof AppGameContainer) {
			app = (AppGameContainer) gc;
		}

      
         i = gc.getInput();   //INPUT

Ok so keyTyped would not work how I wanted.

Is there another method so that if the player press ONES he moves 32 Pixel? Else 16.

#5

Oh I’ve never used Slick so I can’t help much ;D

#6

One way you can handle this problem is using the delta time (provided in the update method) to calculate how long a key is pressed.

so something like

if (input.isKeyDown(Input.KEY_LEFT)) {
leftButtonDownTime += delta;
}

Then depending on how long its held down you move 16px or 32px.

Hope that helps.

#7

Check out if your program received your press first (by put in System.out.println). If yes, something wrong with your move method.

EDIT: Ok I tested it some time and it doesnt is really negative so I let it this way. Thanks Kappa.

Yeah good idea!!
It work with just one beautyerror.

So if I press once he move 32px.
BUT if I hold pressed he moves ONE time 32px and after that 16px.
Yes I know why, because of my If(). But I dont know how to change it.
But I think I could live with it. First xD
I made it this way:


public void update(GameContainer gc, int delta) throws SlickException
    {

     START = System.currentTimeMillis();

     checkBewegung();
     checkMessageBox();
     checkMapTeleport();
     checkMechanik(gc);
     checkNPC(); //NPCs und Truhen prüfen

     delta=10;


     if (i.isKeyDown(Input.KEY_LEFT)) 
       leftButtonDownTime += delta;
     

  
     AUSFUEHR = System.currentTimeMillis()-START;

     if(60 > (int)AUSFUEHR)
             gc.sleep(60-(int)AUSFUEHR);


    }

Movement Method:


 else if(LEFT && schalter.player_x>0
             && blocked[schalter.player_x][schalter.player_y+48] ==false
             && blocked[schalter.player_x][schalter.player_y+61] ==false
             && schalter.BewegungErlaubt )
     {

            if(leftButtonDownTime<10){
              p.x=p.x+32;
             schalter.player_x=schalter.player_x-32;
            }

        else {
           p.x=p.x+16;
          schalter.player_x=schalter.player_x-16;
         }

      }

In the keyPressed I just did


case Input.KEY_LEFT:
                      LEFT=false;
                      TypedLEFT=false;
                      benutzt=false;
                      bewegung=false;
                      leftButtonDownTime=0;
                      break;
